Typical valve parameters
| Parameter | Typical Specification |
|---|---|
| Body material | 304, 316L (CF8, CF3M, F304, F316L) |
| Internal finish | Mechanically polished Ra 0.8 µm; electropolished Ra 0.4 µm on request |
| Seat and seal | PTFE, EPDM, silicone, FKM, selected by product and cleaning agent |
| Connections | Tri-clamp (ISO 2852), DIN 11851, SMS, welded tube ends |
| Size range | 1/2 inch to 4 inch (DN15 to DN100) for ball valves; DN25 to DN200 for butterfly valves |
| Working temperature | -10 °C to +150 °C, depending on seal; steam sterilisation to about 135 °C |
| Pressure rating | Typically 10 to 16 bar for hygienic valves, depending on connection |
| Operation | Lever, locking lever, pneumatic or electric actuator |
Match the seal to the fat content. EPDM resists hot water, steam and cleaning chemicals, but it swells in oils and fats. FKM and PTFE resist oils. Silicone is soft and neutral but has low mechanical strength. Choosing the wrong seal is one of the most common causes of premature valve failure in food plants.
Complete Valve and Fitting Packages for Processing Lines
A processing line needs more than ball valves. It needs butterfly valves for large flows, check valves for pump discharge, sampling valves for quality control, strainers to protect pumps, sight glasses to see product, and fittings of every kind. We supply these as matched sets from one factory, so surfaces, seals and documents are consistent.
| Product | Size Range | Typical Position in the Line |
|---|---|---|
| Tri-clamp ball valves, 2-piece and 3-piece | 1/2 inch to 4 inch | Product lines, tank outlets, cleaning circuits |
| Sanitary butterfly valves | DN25 to DN200 | Large flow lines, tank bottoms |
| Sanitary check valves | 1/2 inch to 4 inch | Pump discharge, backflow prevention |
| Sampling valves | 1/2 inch to 1 inch | Quality control points |
| Sanitary Y-strainers and filters | 1/2 inch to 4 inch | Protection of pumps and fillers |
| Sight glasses | 1 inch to 4 inch | Visual inspection of flow and colour |
| Three-way and diverter valves | 1/2 inch to 3 inch | Product routing, cleaning circuits |
| Fittings: elbows, tees, reducers, ferrules, clamps, gaskets | 1/2 inch to 4 inch | All connections |
| Tank accessories: spray balls, manways, vents | On request | Tank equipment for processing vessels |
Typical process areas
- Receiving and raw material handling: transfer lines from tankers and tanks.
- Mixing and blending: dosing of ingredients, additive lines.
- Heat treatment: pasteurisers, cookers, sterilisers, cooling tunnels.
- Filling and packaging: filler supply lines, product return lines.
- Utilities: steam, compressed air, chilled water, CIP supply and return.
Send us the process flow diagram or a list of lines with product and temperature. We will propose a standard set of valves for each area, with a clear parts list.
Hygiene, Food Contact and Quality System Standards
Food factories operate under food safety regulations and audit schemes, and these influence what is accepted for equipment. Suppliers of valves are asked to prove that materials are suitable, that surfaces are cleanable and that production is controlled. The references below are those most often requested.
| Area | Standard Reference |
|---|---|
| Food contact materials, EU | Regulation (EC) 1935/2004, Regulation (EC) 2023/2006 (good manufacturing practice), Regulation (EU) 10/2011 for plastics |
| Food contact materials, United States | FDA 21 CFR 177 (plastics and elastomers) |
| Hygienic design of equipment | EHEDG guidelines, EN 1672-2, ISO 14159 |
| Sanitary standards | 3-A Sanitary Standards, ASME BPE (for bioprocessing) |
| Hygienic connections | ISO 2852 (clamp), DIN 11851, SMS, DIN 32676 |
| Stainless steel material | ASTM A351 CF8 / CF3M, ASTM A182 F304 / F316L, EN 10088 |
| Surface finish and passivation | ISO 4287, ASTM A967 |
| Hazard analysis | HACCP principles (Codex Alimentarius) |
| Food safety management and audit schemes | ISO 22000, FSSC 22000, BRCGS, IFS |
| Pressure testing | API 598, EN 12266-1, ISO 5208 |
Valves do not carry a "BRC certificate". Audit schemes such as BRCGS and FSSC 22000 apply to food manufacturers and some suppliers, and their auditors check whether equipment suppliers can show compliance of materials, traceability and hygiene. We help our customers with documents that answer these questions.
Hygienic design is a discipline of its own. Short dead legs, drainability, smooth welds and crevice-free seals matter as much as the finish of the valve body. We advise on piping layout where it affects valve choice.
Reference note: food safety rules and customer audit schemes change over time, and large brand owners often add their own equipment requirements. Send us the requirement list when you ask for a quotation. We will mark each item as met, met with documents, or not applicable, so you can see our position at a glance.
Supplier Approval Documents for Food Plants
Large food and beverage companies have strict supplier approval procedures. A valve supplier may need to fill in a questionnaire, send material declarations and pass an audit. We prepare a standard approval pack so that this process is quick and complete, and we adapt it to each customer's format.
- Declaration of conformity for food contact: for stainless steel and seals, referencing Regulation (EC) 1935/2004 and FDA rules where applicable.
- Seal compliance statements: FDA, EU and, where required, 3-A or USP Class VI documents from PTFE, EPDM, silicone and FKM suppliers.
- Material certificate: EN 10204 3.1 for body and trim, with heat numbers.
- Surface finish and passivation records: roughness measurements and passivation certificate.
- Allergen and cleaning statement: information on lubricants and cleaning agents used in production, stating that no allergens are used in the process.
- Pressure test report: shell and seat tests per API 598 or EN 12266-1.
- Traceability procedure: description of how lots are tracked from materials to shipment.
- Quality system information: ISO 9001 style system, with audit access on request.
- Third-party inspection: SGS, BV, TUV or the customer's auditor can visit our factory.
Lubricants matter. Machining oil and assembly grease can contaminate a food product if they are not food-safe. We use food-grade lubricants in assembly of hygienic valves, clean valves after machining and bag them before packing.
Sample approval packs can be sent before your first order.
Audit tip: prepare a supplier file for each valve family, with the declaration of conformity, seal statements, material certificates and surface reports. When a customer or certification body audits your plant, you can show the file within minutes, and the audit moves forward without long searches for old documents.
Lot Traceability for Recall Readiness
Food companies live with the possibility of a recall, and they expect suppliers to support them with good records. If a valve component is suspected of contaminating a product, the plant needs to know quickly which lot it came from and where else that lot was used. Our traceability system is designed to give that answer.
- Stainless steel: heat numbers and mill certificates are recorded for body, ferrule and trim, with PMI checks.
- Seals and gaskets: supplier lot numbers and compliance documents are recorded for each seal batch.
- Polishing and passivation: batch records connect each valve lot to its surface treatment.
- Assembly: assembly sheet lists body heat, seal lot and lubricant, with date and operator.
- Packing: cartons are labelled with lot number, linked to the packing list.
- Shipping record: lot numbers by customer and date, so that affected shipments can be found quickly.
| Component | Record Kept | Purpose |
|---|---|---|
| Body and ferrule | Heat number, certificate | Proof of grade |
| Seals | Supplier lot, compliance document | Proof of food contact compliance |
| Lubricant | Product and batch | Proof of food-grade lubricant |
| Surface | Roughness and passivation record | Proof of cleanability |
| Carton | Lot number | Link to shipment |
These records can be adapted to the coding system of your plant, so that valves and spare parts enter your maintenance system with full traceability from the beginning.
Why lubricant records help: a stray non-food-grade lubricant is a common audit finding. By recording the lubricant type used for each lot, and by using only food-grade products in the hygienic assembly area, we remove that risk, and we can show the record to an auditor whenever it is requested.
Testing and Hygiene Verification
Valves for food processing are pressure tested like any industrial valve, and checked for surface quality, cleanliness and seal condition. We also test where it matters to production, for example the torque needed to operate with a viscous product, and the behaviour of seals in hot cleaning solutions.
| Test | Method | Frequency |
|---|---|---|
| Shell and seat test | Water or air per API 598 / EN 12266-1 | 100% of valves |
| Surface roughness | Portable profilometer on bore and sealing faces | Sampling |
| Visual inspection | Under light for scratches, pits, weld defects and polishing marks | 100% of valves |
| PMI | XRF analyser | Incoming and sampling |
| Passivation check | Copper sulfate or ferroxyl test | Per batch |
| Seal check | Hardness test and visual inspection | Per seal lot |
| Cleanliness | Ultrasonic cleaning, drying, wipe test | 100% for hygienic valves, wipe test on samples |
| Seal compatibility test | Immersion of sample seal in customer's product or cleaning agent | On request |
| Cycle test | Repeated operation, then leakage check | Type test |
CIP chemistry check. Caustic soda at 70 to 85 °C, followed by nitric or phosphoric acid and hot water rinses, is standard in many plants. We can run a simple immersion test on sample seals in your cleaning solution at your temperature, and share the result before you place a large order.
You are welcome to inspect our testing, and we can send photos or video of roughness measurement and pressure tests.
Reading the cleaning test: a seal immersion test measures how much a sample gains or loses weight and hardness after exposure to hot cleaning solutions. Small changes mean the seal is stable. Large changes mean it will not last, and a different compound should be chosen before the valves are installed on the line.
Frequently Asked Questions about Food and Beverage Processing Valves
Q: Which stainless steel should I choose for food processing?
304 suits most neutral and mildly acidic products. 316L is better for salty, very acidic or chlorinated products, and for plants that use strong cleaning chemicals.
Q: What valve is best for viscous products like sauces?
A full bore ball valve or a butterfly valve with a large opening. Avoid designs with small passages or pockets where product can stick.
Q: Why do rubber seals fail in oil and fat products?
EPDM swells in oils and fats. Use FKM or PTFE seals for those products, and check compatibility with the cleaning agents.
Q: Can I use the same valves for hot fill and cold fill?
Yes, if the seals suit the highest temperature. Thermal cycling is hard on seals, so check the seal grade, and consider spares for planned replacement.
Q: How often should seals be replaced?
It depends on temperature, chemicals and cycles. Many plants replace gaskets at every annual shutdown, and valve seats at intervals set by inspection and the maintenance plan.
Q: Do you supply valves for mixproof or double seat duty?
We specialise in ball, butterfly, check, sampling and related valves. For double seat mixproof valves, which are a specialised category, please ask and we will tell you honestly whether we can supply or recommend an alternative arrangement.
Q: Are your valves suitable for allergen changeover?
Hygienic valves with smooth, drainable design and cleanable seals support allergen control, but the cleaning procedure and validation belong to the plant. We can help by providing materials information and design advice.

| Payment | 30% T/T deposit, 70% before shipment; L/C at sight for approved accounts |
What affects the price
- Grade: 316L costs more than 304.
- Finish: electropolished surfaces cost more than mechanically polished ones.
- Valve design: 3-piece and sanitary designs have more parts than 2-piece valves.
- Seals: PTFE, FKM and silicone cost more than EPDM.
- Documents: extended compliance packs and audit support add cost.
Total cost of ownership. A cheap valve with a poor finish or the wrong seal can cause downtime, product loss and audit findings. We suggest comparing offers by finish, seal, documents and traceability, not only by price per piece.
Ordering advice: for a new line, order valves, fittings and seal spares together, and ask for a packing list organised by process area. Site crews then find the right parts easily, installation is faster, and the plant avoids a series of small urgent orders during the first weeks of operation.
Lead Time, Customisation, Hygienic Packaging and Trade Terms
Lead time and stock
Standard tri-clamp valves and fittings ship in 10 to 20 days. Custom finishes, special connections, actuated packages and valve manifolds usually need 25 to 45 days. For shutdown projects, tell us the date, and we will plan production backward from it.
Customisation
We can customise connection type, finish, seal material, handle colour, laser marking, actuator, manifold layout and packaging. For OEM equipment makers, we can supply valves for tank outlets, filler stations and skid-mounted systems, according to your drawings.
Hygienic packaging
- Each valve cleaned, dried and sealed in a clean bag
- Protective covers on ends and ferrules
- Inner cartons with dividers, export cartons on pallets
- Labels with size, grade, seal material and lot
- Neutral or customer-branded packing
Shipping and trade terms
| Term | Details |
|---|---|
| Incoterms | EXW, FOB Ningbo, CFR, CIF, DAP |
| Port | Ningbo-Zhoushan; Shanghai as an alternative |
| Transport | Sea freight, air freight for urgent items, express courier for samples |
| Documents | Invoice, packing list, bill of lading, origin certificate, material and test certificates |
We can combine food and beverage valves with other stainless products in one container, and send documents in advance for customs and supplier approval.
Handling advice: keep valves in their bags until installation, use gloves and clean tools, and flush and sanitise the line before the first production run. After each cleaning cycle, inspect gaskets for wear, and keep a record of replacements, which helps with both maintenance planning and food safety audits.
